National Cotton Production Meteorology Monthly Report (October 2014)

Project commitment: National Meteorological Center

Respondents: 13 cotton producing provinces (districts), 201 cotton producing counties and 61 meteorological stations.

Survey time: October 2014

Abstract: at the end of 10, the cotton growing area in northwest, the Yellow River and Yangtze River was in the picking stage, and some areas had stopped growing.

During the month, the average temperature in the cotton growing area of China was 16.6 degrees Celsius, 0.1 and 1.1 degrees higher than that of the previous year and the same period of the year. The average sunshine hours were 184.1 hours, 24.6 hours and 2.6 hours less than that of the previous year and the same period of the year. The average precipitation was 42.2 millimeters, 26.5 mm and 2.2 millimeters higher than that of the previous year and the same year.

During the month, the light and temperature conditions in the northwest cotton region were better, but the early frost appeared in the northern Xinjiang, Hami, Bazhou and parts of Akesu in the early part of the year, which had an adverse effect on cotton quality.

Most of the cotton fields in the the Yellow River River Basin and the Yangtze River Valley are sunny and sunny, which is good for cotton cracking and bolting and picking and drying.

From the end of 10 to the end of cotton planting, the comprehensive climate suitability index of cotton growing areas in China is more suitable.

The average cotton yield per unit area in 2014 is 1440 kg / ha, which is 0.7% less than that in 2013.

Most cotton areas in the country are in the picking stage, and some of them have stopped growing. The growth period of most parts of cotton is 2-8 days ahead of schedule.

Two. Climate suitability analysis of cotton

1. The light and temperature conditions in the large part of the northwest cotton area are better, but the first frost in Hami and other places in Northern Xinjiang has been affected, and the quality of cotton is affected.

The monthly mean temperature in the inland cotton area of Northwest China is 12.5 degrees, 1 degrees lower than that of the same period last year, 1.3 degrees higher than that of the same period of the year. The monthly sunshine hours are 244.4 hours, 22.6 hours and 3.8 hours less than that of the previous year and the same period of the year. The monthly rainfall is 3.9 millimeters, 0.6 mm higher than that of the same period last year, and 1 millimeters less than that of the same period.

During the month, most parts of the northwest cotton area had higher temperature, less rainfall and more sunshine. Meteorological conditions were more favorable for cotton picking.

But at the beginning of the middle part of the year, the early frost appeared early in the northern Xinjiang, Hami and Bazhou and parts of Akesu, which stopped the growth of cotton early and had an adverse effect on cotton quality.

From the end of 10 months to the end of the cotton planting in Northwest China, the comprehensive climate suitability index is more suitable.

The average yield per unit area of cotton in northwest inland area increased by 0.3% compared with 2013.

2. Most of the cotton fields in the the Yellow River River Basin are mainly sunny weather, which is good for cotton cracking, bolting and picking.

The monthly mean temperature in the cotton area of the Yellow River basin is 16.3 degrees, 0.5 and 1 degrees higher than that of the previous year and the same period of the year. The monthly sunshine hours are 141.3 hours.

It is 46.5 hours and 41.3 hours less than the same period of the year, and the monthly rainfall is 30 millimeters, which is more than 13.5 millimeters over the same period last year. It is 4.8 millimeters less than that of the same period.

During the month, most of the cotton fields in the the Yellow River River Basin were mainly sunny weather, which was good for cotton cracking, bolting and picking.

The suitable climate index is suitable for cotton planting in the the Yellow River River Basin till the end of 10.

The average yield per unit area of cotton in the the Yellow River River Basin was 0.6% lower than that in 2013.

3, the Yangtze River Basin cotton area is more fine and less rain, which is good for cotton cracking, bolting and collecting and drying.

The monthly mean temperature of the Yangtze River valley cotton area is 19.5 degrees Celsius, 0.4 and 1.1 degrees higher than that of the previous year and the same period of the year. The monthly sunshine hours are 185.8 hours, 5.7 hours less than that of the same period last year, and 33.5 hours more than the same period of the same year. The monthly rainfall is 77.3 millimeters, which is 54.6 mm and 10.8 mm respectively over the previous year and the same period of the year.

During the month, most of the cotton growing areas in the Yangtze River Valley are sunny and rainy. The temperature is high and the sunshine is adequate. There is no continuous rain and rainy weather.

The suitable climate index is suitable for cotton planting in the Yangtze River Valley till the end of 10.

The average yield per unit area of cotton in the Yangtze River Basin decreased by 3.1% compared with 2013.

Climate Outlook and recommendations for cotton region in three and November

It is estimated that in November,

The temperature in most of the cotton growing areas is almost the same. The temperature in the southeastern part of Xinjiang, the southern part of Henan and the cotton area in Hubei is lower than that in the same period. The precipitation in the Yangtze River Basin is more than that in the same period of the same year. Hubei and the northern part of Hunan are more than 2-5.

On the whole, the weather conditions in most parts of the Yangtze River Basin in November will have some adverse effects on cotton picking, drying and storage and pportation. Most of the weather conditions in Northwest and the Yellow River river basins are more favorable for cotton drying, storage and pportation.

Suggestions: cotton area should grasp the fine weather as soon as possible to finish cotton picking and drying, avoid cooling, and precipitation will affect cotton yield and quality. The cotton picking area must be removed in time to avoid affecting autumn and winter.
